The present invention relates to a nucleic acid sequence, comprising or coding for a coding region, encoding at least one peptide or protein comprising a therapeutic protein or a fragment, variant or derivative thereof, at least one histone stem-loop and a poly(A) sequence or a polyadenylation signal. Furthermore, the present invention provides the use of the nucleic acid for increasing the expression of said encoded peptide or protein, particularly for the use in gene therapy. It also discloses its use for the preparation of a pharmaceutical composition, e.g. for use in gene therapy, particularly in the treatment of diseases which are in need of a treatment with a therapeutic peptide or protein, preferably as defined herein. The present invention further describes a method for increasing the expression of a peptide or protein comprising a therapeutic protein or a fragment, variant or derivative thereof, using the nucleic acid comprising or coding for a histone stem-loop and a poly(A) sequence or a polyadenylation signal.

Gene therapy means the use of nucleic acids as a pharmaceutical agent to treat a disease. It derives its name from the idea that nucleic acids can be used to supplement or alter the expression of a gene within an individual's cells as a therapy to treat a disease. The most common form of gene therapy involves using nucleic acids that encode a functional, therapeutic protein in order to replace a mutated gene. Other forms involve direct correction of a mutation, or using nucleic acids that encode a therapeutic protein drug to provide treatment.

Gene therapy is a method of molecular medicine which already has been proven in the therapy and prevention of diseases and generally exhibits a considerable effect on daily medical practice, in particular on the treatment of diseases as mentioned herein. Gene therapy is based on the introduction of nucleic acids into the patient's cells or tissue and subsequent processing of the information coded for by the nucleic acid that has been introduced into the cells or tissue, that is to say the (protein) expression of the desired polypeptides.

Gene therapy may be beneficial for a lot of inherited or acquired diseases, inter alia infectious diseases, neoplasms (e.g. cancer or tumour diseases), diseases of the blood and blood-forming organs, endocrine, nutritional and metabolic diseases, diseases of the nervous system, diseases of the circulatory system, diseases of the respiratory system, diseases of the digestive system, diseases of the skin and subcutaneous tissue, diseases of the musculoskeletal system and connective tissue, and diseases of the genitourinary system.

In gene therapy approaches, typically DNA is used even though RNA is also known in recent developments. Importantly, in all these gene therapy approaches mRNA functions as messenger for the sequence information of the encoded protein, irrespectively if DNA, viral RNA or mRNA is used.

In general RNA is considered an unstable molecule: RNases are ubiquitous and notoriously difficult to inactivate. Furthermore, RNA is also chemically more labile than DNA. Thus, it is perhaps surprising that the “default state” of an mRNA in a eukaryotic cell is characterized by a relative stability and specific signals are required to accelerate the decay of individual mRNAs. The main reason for this finding appears to be that mRNA decay within cells is catalyzed almost exclusively by exonucleases. However, the ends of eukaryotic mRNAs are protected against these enzymes by specific terminal structures and their associated proteins: a m7GpppN CAP at the 5′ end and typically a poly(A) sequence at the 3′ end. Removal of these two terminal modifications is thus considered rate limiting for mRNA decay. Although a stabilizing element has been characterized in the 3′ UTR of the alpha-globin mRNA, RNA sequences affecting turnover of eukaryotic mRNAs typically act as a promoter of decay usually by accelerating deadenylation (reviewed in Meyer, S., C. Temme, et al. (2004), Crit Rev Biochem Mol Biol 39(4): 197-216.).

As mentioned above, the 5′ ends of eukaryotic mRNAs are typically modified posttranscriptionally to carry a methylated CAP structure, e.g. m7GpppN. Aside from roles in RNA splicing, stabilization, and transport, the CAP structure significantly enhances the recruitment of the 40S ribosomal subunit to the 5′ end of the mRNA during translation initiation. The latter function requires recognition of the CAP structure by the eukaryotic initiation factor complex eIF4F. The poly(A) sequence additionally stimulates translation via increased 40S subunit recruitment to mRNAs, an effect that requires the intervention of poly(A) binding protein (PABP). PABP, in turn, was recently demonstrated to interact physically with eIF4G, which is part of the CAP-bound eIF4F complex. Thus, a closed loop model of translation initiation on capped, polyadenylated mRNAs was postulated (Michel, Y. M., D. Poncet, et al. (2000), J Biol Chem 275(41): 32268-76.).

Nearly all eukaryotic mRNAs end with such a poly(A) sequence that is added to their 3′ end by the ubiquitous cleavage/polyadenylation machinery. The presence of a poly(A) sequence at the 3′ end is one of the most recognizable features of eukaryotic mRNAs. After cleavage, most pre-mRNAs, with the exception of replication-dependent histone transcripts, acquire a polyadenylated tail. In this context, 3′ end processing is a nuclear co-transcriptional process that promotes transport of mRNAs from the nucleus to the cytoplasm and affects the stability and the translation of mRNAs. Formation of this 3′ end occurs in a two step reaction directed by the cleavage/polyadenylation machinery and depends on the presence of two sequence elements in mRNA precursors (pre-mRNAs); a highly conserved hexanucleotide AAUAAA (polyadenylation signal) and a downstream G/U-rich sequence. In a first step, pre-mRNAs are cleaved between these two elements. In a second step tightly coupled to the first step the newly formed 3′ end is extended by addition of a poly(A) sequence consisting of 200-250 adenylates which affects subsequently all aspects of mRNA metabolism, including mRNA export, stability and translation (Dominski, Z. and W. F. Marzluff (2007), Gene 396(2): 373-90.).

The only known exception to this rule are the replication-dependent histone mRNAs which end with a histone stem-loop instead of a poly(A) sequence. Exemplary histone stem-loop sequences are described in Lopez et al. (Dávila López, M., & Samuelsson, T. (2008), RNA (New York, N.Y.), 14(1), 1-10. doi:10.1261/rna.782308.).

The stem-loops in histone pre-mRNAs are typically followed by a purine-rich sequence known as the histone downstream element (HDE). These pre-mRNAs are processed in the nucleus by a single endonucleolytic cleavage approximately 5 nucleotides downstream of the stem-loop, catalyzed by the U7 snRNP through base pairing of the U7 snRNA with the HDE. The 3′-UTR sequence comprising the histone stem-loop structure and the histone downstream element (HDE) (binding site of the U7 snRNP) were usually termed as histone 3′-processing signal (see e.g. Chodchoy, N., N. B. Pandey, et al. (1991). Mol Cell Biol 11(1): 497-509.).

Due to the requirement to package newly synthesized DNA into chromatin, histone synthesis is regulated in concert with the cell cycle. Increased synthesis of histone proteins during S phase is achieved by transcriptional activation of histone genes as well as posttranscriptional regulation of histone mRNA levels. It could be shown that the histone stem-loop is essential for all posttranscriptional steps of histone expression regulation. It is necessary for efficient processing, export of the mRNA into the cytoplasm, loading onto polyribosomes, and regulation of mRNA stability.

In the above context, a 32 kDa protein was identified, which is associated with the histone stem-loop at the 3′-end of the histone messages in both the nucleus and the cytoplasm. The expression level of this stem-loop binding protein (SLBP) is cell-cycle regulated and is highest during S-phase when histone mRNA levels are increased. SLBP is necessary for efficient 3′-end processing of histone pre-mRNA by the U7 snRNP. After completion of processing, SLBP remains associated with the stem-loop at the end of mature histone mRNAs and stimulates their translation into histone proteins in the cytoplasm. (Dominski, Z. and W. F. Marzluff (2007), Gene 396(2): 373-90). Interestingly, the RNA binding domain of SLBP is conserved throughout metazoa and protozoa (Dávila López, M., & Samuelsson, T. (2008), RNA (New York, N.Y.), 14(1), 1-10. doi:10.1261/rna.782308) and it could be shown that its binding to the histone stem-loop sequence is dependent on the stem-loop structure and that the minimum binding site contains at least 3 nucleotides 5′ and 2 nucleotides 3′ of the stem-loop (Pandey, N. B., et al. (1994), Molecular and Cellular Biology, 14(3), 1709-1720 and Williams, A. S., & Marzluff, W. F., (1995), Nucleic Acids Research, 23(4), 654-662.).

Even though histone genes are generally classified as either “replication-dependent”, giving rise to mRNA ending in a histone stem-loop, or “replacement-type”, giving rise to mRNA bearing a poly(A)-tail instead, naturally occurring mRNAs containing both a histone stem-loop and poly(A) or oligo(A) 3′ thereof have been identified in some very rare cases. Sanchez et al. examined the effect of naturally occurring oligo(A) tails appended 3′ of the histone stem-loop of histone mRNA during Xenopus oogenesis using Luciferase as a reporter protein and found that the oligo(A) tail is an active part of the translation repression mechanism that silences histone mRNA during oogenesis and its removal is part of the mechanism that activates translation of histone mRNAs (Sanchez, R. and W. F. Marzluff (2004), Mol Cell Biol 24(6): 2513-25).

Furthermore, the requirements for regulation of replication dependent histones at the level of pre-mRNA processing and mRNA stability have been investigated using artificial constructs coding for the marker protein alpha Globin, taking advantage of the fact that the globin gene contains introns as opposed to the intron-less histone genes. For this purpose constructs were generated in which the alpha globin coding sequence was followed by a histone stem-loop signal (histone stem-loop followed by the histone downstream element) and a polyadenylation signal (Whitelaw, E., et al. (1986). Nucleic Acids Research, 14(17), 7059-7070.; Pandey, N. B., & Marzluff, W. F. (1987). Molecular and Cellular Biology, 7(12), 4557-4559.; Pandey, N. B., et al. (1990). Nucleic Acids Research, 18(11), 3161-3170).

In another approach Lüscher et al. investigated the cell-cycle dependent regulation of a recombinant histone H4 gene. Constructs were generated in which the H4 coding sequence was followed by a histone stem-loop signal and a polyadenylation signal, the two processing signals incidentally separated by a galactokinase coding sequence (Lüscher, B. et al., (1985). Proc. Natl. Acad. Sci. USA, 82(13), 4389-4393).

Additionally, Stauber et al. identified the minimal sequence required to confer cell-cycle regulation on histone H4 mRNA levels. For these investigations constructs were used, comprising a coding sequence for the selection marker Xanthine:guanine phosphoribosyl transferase (GPT) preceding a histone stem-loop signal followed by a polyadenylation signal (Stauber, C. et al., (1986). EMBO J, 5(12), 3297-3303).

Examining histone pre-mRNA processing Wagner et al. identified factors required for cleavage of histone pre-mRNAs using a reporter construct placing EGFP between a histone stem-loop signal and a polyadenylation signal, such that EGFP was expressed only in case histone pre-mRNA processing was disrupted (Wagner, E. J. et al., (2007). Mol Cell 28(4), 692-9).

To be noted, translation of polyadenylated mRNA usually requires the 3′ poly(A) sequence to be brought into proximity of the 5′ CAP. This is mediated through protein-protein interaction between the poly(A) binding protein and eukaryotic initiation factor eIF4G. With respect to replication-dependent histone mRNAs, an analogous mechanism has been uncovered. In this context, Gallie et al. show that the histone stem-loop is functionally similar to a poly(A) sequence in that it enhances translational efficiency and is co-dependent on a 5′-CAP in order to establish an efficient level of translation. They showed that the histone stem-loop is sufficient and necessary to increase the translation of a reporter mRNA in transfected Chinese hamster ovary cells but must be positioned at the 3′-terminus in order to function optimally. Therefore, similar to the poly(A) tail on other mRNAs, the 3′ end of these histone mRNAs appears to be essential for translation in vivo and is functionally analogous to a poly(A) tail (Gallie, D. R., Lewis, N. J., & Marzluff, W. F. (1996), Nucleic Acids Research, 24(10), 1954-1962).

Additionally, it could be shown that SLBP is bound to the cytoplasmic histone mRNA and is required for its translation. Even though SLBP does not interact directly with eIF4G, the domain required for translation of histone mRNA interacts with the recently identified protein SLIP1. In a further step, SLIP1 interacts with eIF4G and allows to circularize histone mRNA and to support efficient translation of histone mRNA by a mechanism similar to the translation of polyadenylated mRNAs.

As mentioned above, gene therapy approaches normally use DNA to transfer the coding information into the cell which is then transcribed into mRNA, carrying the naturally occurring elements of an mRNA, particularly the 5′-CAP structure and the 3′ poly(A) sequence to ensure expression of the encoded therapeutic or antigenic protein.

However, in many cases expression systems based on the introduction of such nucleic acids into the patient's cells or tissue and the subsequent expression of the desired polypeptides coded for by these nucleic acids do not exhibit the desired, or even the required, level of expression which may allow for an efficient therapy, irrespective as to whether DNA or RNA is used.

In the prior art, different attempts have hitherto been made to increase the yield of the expression of an encoded protein, in particular by use of improved expression systems, both in vitro and/or in vivo. Methods for increasing expression described generally in the prior art are conventionally based on the use of expression vectors or cassettes containing specific promoters and corresponding regulation elements. As these expression vectors or cassettes are typically limited to particular cell systems, these expression systems have to be adapted for use in different cell systems. Such adapted expression vectors or cassettes are then usually transfected into the cells and typically treated in dependence of the specific cell line. Therefore, preference is given primarily to those nucleic acid molecules which are able to express the encoded proteins in a target cell by systems inherent in the cell, independent of promoters and regulation elements which are specific for particular cell types. In this context, there can be distinguished between mRNA stabilizing elements and elements which increase translation efficiency of the mRNA.

mRNAs which are optimized in their coding sequence and which are in general suitable for such a purpose are described in application WO 02/098443 (CureVac GmbH). For example, WO 02/098443 describes mRNAs that are stabilised in general form and optimised for translation in their coding regions. WO 02/098443 further discloses a method for determining sequence modifications. WO 02/098443 additionally describes possibilities for substituting adenine and uracil nucleotides in mRNA sequences in order to increase the guanine/cytosine (G/C) content of the sequences. According to WO 02/098443, such substitutions and adaptations for increasing the G/C content can be used for gene therapeutic applications but also genetic vaccines in the treatment of cancer or infectious diseases. In this context, WO 02/098443 generally mentions sequences as a base sequence for such modifications, in which the modified mRNA codes for at least one biologically active peptide or polypeptide, which is translated in the patient to be treated, for example, either not at all or inadequately or with faults. Alternatively, WO 02/098443 proposes mRNAs coding for antigens e.g. therapeutic proteins or viral antigens as a base sequence for such modifications.

In a further approach to increase the expression of an encoded protein the application WO 2007/036366 describes the positive effect of long poly(A) sequences (particularly longer than 120 bp) and the combination of at least two 3′ untranslated regions of the beta globin gene on mRNA stability and translational activity.

However, even though all these latter prior art documents already try to provide quite efficient tools for gene therapy approaches and additionally improved mRNA stability and translational activity, there still remains the problem of a generally lower stability of RNA-based applications versus DNA vaccines and DNA based gene therapeutic approaches. Accordingly, there still exists a need in the art to provide improved tools for gene therapy approaches or as a supplementary therapy for conventional treatments as discussed above, which allow for better provision of encoded proteins in vivo, e.g. via a further improved mRNA stability and/or translational activity, preferably for gene therapy.

Furthermore despite of all progress in the art, efficient expression of an encoded peptide or protein in cell-free systems, cells or organisms (recombinant expression) is still a challenging problem.

The object underlying the present invention is, therefore, to provide additional and/or alternative methods to increase expression of an encoded protein, preferably via further stabilization of the mRNA and/or an increase of the translational efficiency of such an mRNA with respect to such nucleic acids known from the prior art for the use in gene therapy in the therapeutic or prophylactic treatment of inherited or acquired diseases, particularly as defined herein.

This object is solved by the subject matter of the attached claims. Particularly, the object underlying the present invention is solved according to a first aspect by an inventive nucleic acid sequence comprising or coding for

-   -   a) a coding region, encoding at least one peptide or protein         which comprises a therapeutic protein or a fragment, variant or         derivative thereof;     -   b) at least one histone stem-loop, and     -   c) a poly(A) sequence or a polyadenylation signal,         preferably for increasing the expression of said encoded peptide         or protein.

Alternatively, any appropriate stem loop sequence other than a histone stem loop sequence (derived from histone genes, in particular histone genes of the families H1, H2A, H2B, H3 and H4) may be employed by the present invention in all of its aspects and embodiments.

In this context it is particularly preferred that the inventive nucleic acid according to the first aspect of the present invention is produced at least partially by DNA or RNA synthesis, preferably as described herein or is an isolated nucleic acid.

The present invention is based on the surprising finding of the present inventors, that the combination of a poly(A) sequence or polyadenylation signal and at least one histone stem-loop, even though both representing alternative mechanisms in nature, acts synergistically as this combination increases the protein expression manifold above the level observed with either of the individual elements. The synergistic effect of the combination of poly(A) and at least one histone stem-loop is seen irrespective of the order of poly(A) and histone stem-loop and irrespective of the length of the poly(A) sequence.

Therefore it is particularly preferred that the inventive nucleic acid sequence comprises or codes for a) a coding region, encoding at least one peptide or protein which comprises a therapeutic protein or a fragment, variant or derivative thereof; b) at least one histone stem-loop, and c) a poly(A) sequence or polyadenylation sequence; preferably for increasing the expression level of said encoded peptide or protein, wherein the encoded protein is preferably no histone protein, in particular no histone protein of the H4, H3, H2A and/or H2B histone family or a fragment, derivative or variant thereof retaining histone(-like) function), namely forming a nucleosome.

Also, the encoded protein typically does not correspond to a histone linker protein of the H1 histone family. The inventive nucleic acid molecule does typically not contain any regulatory signals (5′ and/or, particularly, 3′) of a mouse histone gene, in particular not of a mouse histone gene H2A and, further, most preferably not of the mouse histone gene H2A614. In particular, it does not contain a histone stem loop and/or a histone stem loop processing signal from a mouse histone gene, in particular not of mouse histone gene H2A und, most preferably not of mouse histone gene H2A614.

Also, the inventive nucleic acid typically does not provide a reporter protein (e.g. Luciferase, GFP, EGFP, β-Galactosidase, particularly EGFP), galactokinase (galK) and/or marker or selection protein (e.g. alpha-Globin, Galactokinase and Xanthine:Guanine phosphoribosyl transferase (GPT)) or a bacterial reporter protein, e.g. chloramphenicol acetyl transferase (CAT) or other bacterial antibiotics resistance proteins, e.g. derived from the bacterial neo gene in its element (a).

A reporter, marker or selection protein is typically understood not to be a therapeutic protein according to the invention. A reporter, marker or selection protein or its underlying gene is commonly used as a research tool in bacteria, cell culture, animals or plants. They confer on organisms (preferably heterologously) expressing them an easily identifiable property, which may be measured or which allows for selection. Specifically, marker or selection proteins exhibit a selectable function. Typically, such selection, marker or reporter proteins do not naturally occur in humans or other mammals, but are derived from other organisms, in particular from bacteria or plants. Accordingly, proteins with selection, marker or reporter function originating from species other than mammals, in particular other than humans, are preferably excluded from being understood as “therapeutic protein” according to the present invention. In particular, a selection, marker or reporter protein allows to identify transformed cells by in vitro assays based e.g. on fluorescence or other spectroscopic techniques and resistance towards antibiotics. Selection, reporter or marker genes awarding such properties to transformed cells are therefore typically not understood to be a therapeutic protein according to the invention.

In any case, reporter, marker or selection proteins do usually not exert any therapeutic effect. If any single reporter, marker or selection protein should nevertheless do so (in addition to its reporter, selection or marker function), such a reporter, marker or selection protein is preferably not understood to be a “therapeutic protein” within the meaning of the present invention.

In contrast, a therapeutic protein (including its fragments, variants and derivatives), in particular excluding histone genes of the families H1, H2A, H2B, H3 and H4, according to the present invention does typically not exhibit a selection, marker or reporter function. If any single “therapeutic protein” nevertheless should do so (in addition to its therapeutic function), such a therapeutic protein is preferably not understood to be a “selection, marker or reporter protein” within the meaning of the present invention.

It is most preferably understood that a therapeutic protein according to the invention is derived from mammals, in particular humans, and does not qualify as selection, marker or reporter protein.

Accordingly, it is preferred that the coding region (a) encoding at least one peptide or protein is heterologous to at least (b) the at least one histone stem loop, or more broadly, to any appropriate stem loop. In other words, “heterologous” in the context of the present invention means that the at least one stem loop sequence does not naturally occur as a (regulatory) sequence (e.g. at the 3′UTR) of the specific gene, which encodes the (therapeutic) protein or peptide of element (a) of the inventive nucleic acid. Accordingly, the (histone) stem loop of the inventive nucleic acid is derived preferably from the 3′ UTR of a gene other than the one comprising the coding region of element (a) of the inventive nucleic acid. E.g., the coding region of element (a) will not encode a histone protein or a fragment, variant or derivative thereof (retaining the function of a histone protein), if the inventive nucleic is heterologous, but will encode any other peptide or sequence (of the same or another species) which exerts a biological function, preferably therapeutic function other than a histone(-like) function, e.g. will encode an therapeutic protein (exerting a therapeutic function, e.g. in terms endocrine disorders, replacing defective endogenous, e.g. mammalian, in particular human proteins).

In this context it is particularly preferred that the inventive nucleic acid comprises or codes for in 5′- to 3′-direction:

-   -   a) a coding region, encoding at least one peptide or protein         which comprises a therapeutic protein or a fragment, variant or         derivative thereof;     -   b) at least one histone stem-loop, optionally without a histone         downstream element (HDE) 3′ to the histone stem-loop     -   c) a poly(A) sequence or a polyadenylation signal.

The term “histone downstream element (HDE) refers to a purine-rich polynucleotide stretch of about 15 to 20 nucleotides 3′ of naturally occurring histone stem-loops, which represents the binding site for the U7 snRNA involved in processing of histone pre-mRNA into mature histone mRNA. For example in sea urchins the HDE is CAAGAAAGA (Dominski, Z. and W. F. Marzluff (2007), Gene 396(2): 373-90).

Furthermore it is preferable that the inventive nucleic acid according to the first aspect of the present invention does not comprise an intron.

In another particular preferred embodiment, the inventive nucleic acid sequence according to the first aspect of the present invention comprises or codes for from 5′ to 3′:

-   -   a) a coding region, preferably encoding at least one peptide or         protein which comprises a therapeutic protein or a fragment,         variant or derivative thereof;     -   c) a poly(A) sequence; and     -   b) at least one histone stem-loop.

The inventive nucleic acid sequence according to the first embodiment of the present invention comprise any suitable nucleic acid, selected e.g. from any (single-stranded or double-stranded) DNA, preferably, without being limited thereto, e.g. genomic DNA, plasmid DNA, single-stranded DNA molecules, double-stranded DNA molecules, or may be selected e.g. from any PNA (peptide nucleic acid) or may be selected e.g. from any (single-stranded or double-stranded) RNA, preferably a messenger RNA (mRNA); etc. The inventive nucleic acid sequence may also comprise a viral RNA (vRNA). However, the inventive nucleic acid sequence may not be a viral RNA or may not contain a viral RNA. More specifically, the inventive nucleic acid sequence may not contain viral sequence elements, e.g. viral enhancers or viral promotors (e.g. no inactivated viral promoter or sequence elements, more specifically not inactivated by replacement strategies), or other viral sequence elements, or viral or retroviral nucleic acid sequences. More specifically, the inventive nucleic acid sequence may not be a retroviral or viral vector or a modified retroviral or viral vector.

In any case, the inventive nucleic acid sequence may or may not contain an enhancer and/or promoter sequence, which may be modified or not or which may be activated or not. The enhancer and or promoter may be plant expressible or not expressible, and/or in eukaryotes expressible or not expressible and/or in prokaryotes expressible or not expressible. The inventive nucleic acid sequence may contain a sequence encoding a (self-splicing) ribozyme or not.

In specific embodiments the inventive nucleic acid sequence may be or may comprise a self-replicating RNA (replicon).

Preferably, the inventive nucleic acid sequence is a plasmid DNA, or an RNA, particularly an mRNA.

In particular embodiments of the first aspect of the present invention, the inventive nucleic acid is a nucleic acid sequence comprised in a nucleic acid suitable for in vitro transcription, particularly in an appropriate in vitro transcription vector (e.g. a plasmid or a linear nucleic acid sequence comprising specific promoters for in vitro transcription such as T3, T7 or Sp6 promoters).

In further particular preferred embodiments of the first aspect of the present invention, the inventive nucleic acid is comprised in a nucleic acid suitable for transcription and/or translation in an expression system (e.g. in an expression vector or plasmid), particularly a prokaryotic (e.g. bacteria like E. coli) or eukaryotic (e.g. mammalian cells like CHO cells, yeast cells or insect cells or whole organisms like plants or animals) expression system.

The term “expression system” means a system (cell culture or whole organisms) which is suitable for production of peptides, proteins or RNA particularly mRNA (recombinant expression).

The inventive nucleic acid sequence according to the first aspect of the present invention comprises or codes for at least one (histone) stem-loop. A stem-loop, in general (irrespective of whether it is a histone stem loop or not), can occur in single-stranded DNA or, more commonly, in RNA. The structure is also known as a hairpin or hairpin loop and usually consists of a stem and a (terminal) loop within a consecutive sequence, wherein the stem is formed by two neighbored entirely or partially reverse complementary sequences separated by a short sequence as sort of spacer, which builds the loop of the stem-loop structure. The two neighbored entirely or partially reverse complementary sequences may be defined as e.g. stem loop elements stem1 and stem2. The stem loop is formed when these two neighbored entirely or partially reverse complementary sequences, e.g. stem loop elements stem1 and stem2, form base-pairs with each other, leading to a double stranded nucleic acid sequence stretch comprising an unpaired loop at its terminal ending formed by the short sequence located between stem loop elements stem1 and stem2 on the consecutive sequence. The unpaired loop thereby typically represents a region of the nucleic acid which is not capable of base pairing with either of these stem loop elements. The resulting lollipop-shaped structure is a key building block of many RNA secondary structures. The formation of a stem-loop structure is thus dependent on the stability of the resulting stem and loop regions, wherein the first prerequisite is typically the presence of a sequence that can fold back on itself to form a paired double strand. The stability of paired stem loop elements is determined by the length, the number of mismatches or bulges it contains (a small number of mismatches is typically tolerable, especially for a longer double stranded stretch), and the base composition of the paired region. In the context of the present invention, a loop length of 3 to 15 bases is conceivable, while a more preferred loop length is 3-10 bases, more preferably 3 to 8, 3 to 7, 3 to 6 or even more preferably 4 to 5 bases, and most preferably 4 bases. The stem sequence forming the double stranded structure typically has a length of between 5 to 10 bases, more preferably, between 5 to 8 bases.

In the context of the present invention, a histone stem-loop is typically derived from histone genes (e.g. genes from the histone families H1, H2A, H2B, H3, H4) and comprises an intramolecular base pairing of two neighbored entirely or partially reverse complementary sequences, thereby forming a stem-loop. Typically, a histone 3′ UTR stem-loop is an RNA element involved in nucleocytoplasmic transport of the histone mRNAs, and in the regulation of stability and of translation efficiency in the cytoplasm. The mRNAs of metazoan histone genes lack polyadenylation and a poly-A tail, instead 3′ end processing occurs at a site between this highly conserved stem-loop and a purine rich region around 20 nucleotides downstream (the histone downstream element, or HDE). The histone stem-loop is bound by a 31 kDa stem-loop binding protein (SLBP—also termed the histone hairpin binding protein, or HBP). Such histone stem-loop structures are preferably employed by the present invention in combination with other sequence elements and structures, which do not occur naturally (which means in untransformed living organisms/cells) in histone genes, but are combined—according to the invention—to provide an artificial, heterologous nucleic acid. Accordingly, the present invention is particularly based on the finding that an artificial (non-native) combination of a histone stem-loop structure with other heterologous sequence elements, which do not occur in histone genes or metazoan histone genes and are isolated from operational and/or regulatory sequence regions (influencing transcription and/or translation) of genes coding for proteins other than histones, provide advantageous effects. Accordingly, one aspect of the invention provides the combination of a histone stem-loop structure with a poly(A) sequence or a sequence representing a polyadenylation signal (3′-terminal of a coding region), which does not occur in metazoan histone genes.

According to another preferred aspect of the invention, a combination of a histone stem-loop structure with a coding region coding for a therapeutic protein, which does, preferably not occur in metazoan histone genes, is provided herewith (coding region and histone stem loop sequence are heterologous). It is preferred, if such therapeutic proteins occur naturally in mammalians, preferably humans. In a still further preferred embodiment, all the elements (a), (b) and (c) of the inventive nucleic acid are heterologous to each other and are combined artificially from three different sources, e.g. (a) the therapeutic protein coding region from a human gene, (b) the histone stem loop from an untranslated region of a metazoan, e.g. mammalian, non-human or human, histone gene and (c) the poly(A) sequence or the polyadenylation signal from e.g. an untranslated region of a gene other than a histone gene and other than the gene coding for the therapeutic protein according to element (a) of such an inventive nucleic acid.

A histone stem loop is, therefore, a stem-loop structure as described herein, which, if preferably functionally defined, exhibits/retains the property of binding to its natural binding partner, the stem-loop binding protein (SLBP—also termed the histone hairpin binding protein, or HBP).

According to the present invention the histone stem loop sequence according to component (b) of claim 1 may not derived from a mouse histone protein. More specifically, the histone stem loop sequence may not be derived from mouse histone gene H2A614. Also, the nucleic acid of the invention may neither contain a mouse histone stem loop sequence nor contain mouse histone gene H2A614. Further, the inventive nucleic acid sequence may not contain a stem-loop processing signal, more specifically, a mouse histone processing signal and, most specifically, may not contain mouse stem loop processing signal H2kA614, even if the inventive nucleic acid sequence may contain at least one mammalian histone gene. However, the at least one mammalian histone gene may not be Seq. ID No. 7 of WO 01/12824.

According to one preferred embodiment of the first inventive aspect, the inventive nucleic acid sequence comprises or codes for at least one histone stem-loop sequence, preferably according to at least one of the following formulae (I) or (II):

formula (I) (stem-loop sequence without stem bordering elements):

formula (II) (stem-loop sequence with stem bordering elements):

wherein:

stem1 or stem2 is a consecutive sequence of 1 to 6, preferably of 2 to 6, bordering elements N₁₋₆ more preferably of 2 to 5, even more preferably of 3 to 5, most preferably of 4 to 5 or 5 N, wherein each N is independently from another selected from a nucleotide selected from A, U, T, G and C, or a nucleotide analogue thereof; stem1 is reverse complementary or partially reverse [N₀₋₂GN₃₋₅] complementary with element stem2, and is a consecutive sequence between of 5 to 7 nucleotides; wherein N₀₋₂ is a consecutive sequence of 0 to 2, preferably of 0 to 1, more preferably of 1 N, wherein each N is independently from another selected from a nucleotide selected from A, U, T, G and C or a nucleotide analogue thereof; wherein N₃₋₅ is a consecutive sequence of 3 to 5, preferably of 4 to 5, more preferably of 4 N, wherein each N is independently from another selected from a nucleotide selected from A, U, T, G and C or a nucleotide analogue thereof, and wherein G is guanosine or an analogue thereof, and may be optionally replaced by a cytidine or an analogue thereof, provided that its complementary nucleotide cytidine in stem2 is replaced by guanosine; loop sequence is located between elements stem1 and stem2, and is [N₀₋₄(U/T)N₀₋₄] a consecutive sequence of 3 to 5 nucleotides, more preferably of 4 nucleotides; wherein each N₀₋₄ is independent from another a consecutive sequence of 0 to 4, preferably of 1 to 3, more preferably of 1 to 2 N, wherein each N is independently from another selected from a nucleotide selected from A, U, T, G and C or a nucleotide analogue thereof; and wherein U/T represents uridine, or optionally thymidine; stem2 is reverse complementary or partially reverse [N₃₋₅CN₀₋₂] complementary with element stem1, and is a consecutive sequence between of 5 to 7 nucleotides; wherein N₃₋₅ is a consecutive sequence of 3 to 5, preferably of 4 to 5, more preferably of 4 N, wherein each N is independently from another selected from a nucleotide selected from A, U, T, G and C or a nucleotide analogue thereof; wherein N₀₋₂ is a consecutive sequence of 0 to 2, preferably of 0 to 1, more preferably of 1 N, wherein each N is independently from another selected from a nucleotide selected from A, U, T, G or C or a nucleotide analogue thereof; and wherein C is cytidine or an analogue thereof, and may be optionally replaced by a guanosine or an analogue thereof provided that its complementary nucleotide guanosine in stem1 is replaced by cytidine;

-   -   wherein     -   stem1 and stem2 are capable of base pairing with each other         forming a reverse complementary sequence, wherein base pairing         may occur between stem1 and stem2, e.g. by Watson-Crick base         pairing of nucleotides A and U/T or G and C or by         non-Watson-Crick base pairing e.g. wobble base pairing, reverse         Watson-Crick base pairing, Hoogsteen base pairing, reverse         Hoogsteen base pairing or are capable of base pairing with each         other forming a partially reverse complementary sequence,         wherein an incomplete base pairing may occur between stem1 and         stem2, on the basis that one or more bases in one stem do not         have a complementary base in the reverse complementary sequence         of the other stem.

In the above context, a wobble base pairing is typically a non-Watson-Crick base pairing between two nucleotides.

In the above context a partially reverse complementary sequence comprises maximally 2, preferably only one mismatch in the stem-structure of the stem-loop sequence formed by base pairing of stem1 and stem2. In other words, stem1 and stem2 are preferably capable of (full) base pairing with each other throughout the entire sequence of stem1 and stem2 (100% of possible correct Watson-Crick or non-Watson-Crick base pairings), thereby forming a reverse complementary sequence, wherein each base has its correct Watson-Crick or non-Watson-Crick base pendant as a complementary binding partner. Alternatively, stem1 and stem2 are preferably capable of partial base pairing with each other throughout the entire sequence of stem1 and stem2, wherein at least about 70%, 75%, 80%, 85%, 90%, or 95% of the 100% possible correct Watson-Crick or non-Watson-Crick base pairings are occupied with the correct Watson-Crick or non-Watson-Crick base pairings and at most about 30%, 25%, 20%, 15%, 10%, or 5% of the remaining bases are unpaired.

Therapeutic proteins as defined herein are peptides or proteins which are beneficial for the treatment of any inherited or acquired disease or which improves the condition of an individual. Particularly, therapeutic proteins plays a big role in the creation of therapeutic agents that could modify and repair genetic errors, destroy cancer cells or pathogen infected cells, treat immune system disorders, treat metabolic or endocrine disorders, among other functions. For instance, Erythropoietin (EPO), a protein hormone can be utilized in treating patients with erythrocyte deficiency, which is a common cause of kidney complications. Furthermore adjuvant proteins, therapeutic antibodies are encompassed by therapeutic proteins and also hormone replacement therapy which is e.g. used in the therapy of women in the menopause. In newer approaches somatic cells of a patient are used to reprogram them into pluripotent stem cells which replace the disputed stem cell therapy. Also these proteins used for reprogramming of somatic cells or used for differentiating of stem cells are defined herein as therapeutic proteins. Furthermore therapeutic proteins may be used for other purposes e.g. wound healing, tissue regeneration, angiogenesis, etc.

Therefore therapeutic proteins can be used for various purposes including treatment of various diseases like e.g. infectious diseases, neoplasms (e.g. cancer or tumour diseases), diseases of the blood and blood-forming organs, endocrine, nutritional and metabolic diseases, diseases of the nervous system, diseases of the circulatory system, diseases of the respiratory system, diseases of the digestive system, diseases of the skin and subcutaneous tissue, diseases of the musculoskeletal system and connective tissue, and diseases of the genitourinary system, independently if they are inherited or acquired.

The coding region of the inventive nucleic acid according to the first aspect of the present invention may occur as a mono-, di-, or even multicistronic nucleic acid, i.e. a nucleic acid which carries the coding sequences of one, two or more proteins or peptides. Such coding sequences in di-, or even multicistronic nucleic acids may be separated by at least one internal ribosome entry site (IRES) sequence, e.g. as described herein or by signal peptides which induce the cleavage of the resulting polypeptide which comprises several proteins or peptides.

According to the first aspect of the present invention, the inventive nucleic acid sequence comprises a coding region, encoding a peptide or protein which comprises a therapeutic protein or a fragment, variant or derivative thereof. Preferably, the encoded therapeutic protein is no histone protein. In the context of the present invention such a histone protein is typically a strongly alkaline protein found in eukaryotic cell nuclei, which package and order the DNA into structural units called nucleosomes. Histone proteins are the chief protein components of chromatin, act as spools around which DNA winds, and play a role in gene regulation. Without histones, the unwound DNA in chromosomes would be very long (a length to width ratio of more than 10 million to one in human DNA). For example, each human cell has about 1.8 meters of DNA, but wound on the histones it has about 90 millimeters of chromatin, which, when duplicated and condensed during mitosis, result in about 120 micrometers of chromosomes.

More preferably, in the context of the present invention such a histone protein is typically defined as a highly conserved protein selected from one of the following five major classes of histones: H1/H5, H2A, H2B, H3, and H4”, preferably selected from mammalian histone, more preferably from human histones or histone proteins. Such histones or histone proteins are typically organised into two super-classes defined as core histones, comprising histones H2A, H2B, H3 and H4, and linker histones, comprising histones H1 and H5.

In this context, linker histones, preferably excluded from the scope of protection of the pending invention, preferably mammalian linker histones, more preferably human linker histones, are typically selected from H1, including H1F, particularly including H1F0, H1FNT, H1FOO, H1FX, and H1H1, particularly including HIST1H1A, HIST1H1B, HIST1H1C, HIST1H1D, HIST1H1E, HIST1H1T; and

Furthermore, core histones, preferably excluded from the scope of protection of the pending invention, preferably mammalian core histones, more preferably human core histones, are typically selected from H2A, including H2AF, particularly including H2AFB1, H2AFB2, H2AFB3, H2AFJ, H2AFV, H2AFX, H2AFY, H2AFY2, H2AFZ, and H2A1, particularly including HIST1H2AA, HIST1H2AB, HIST1H2AC, HIST1H2AD, HIST1H2AE, HIST1H2AG, HIST1H2AI, HIST1H2AJ, HIST1H2AK, HIST1H2AL, HIST1H2AM, and H2A2, particularly including HIST2H2AA3, HIST2H2AC; H2B, including H2BF, particularly including H2BFM, H2BFO, H2BFS, H2BFWT H2B1, particularly including HIST1H2BA, HIST1H2BB, HIST1H2BC, HIST1H2BD, HIST1H2BE, HIST1H2BF, HIST1H2BG, HIST1H2BH, HIST1H2BI, HIST1H2BJ, HIST1H2BK, HIST1H2BL, HIST1H2BM, HIST1H2BN, HIST1H2BO, and H2B2, particularly including HIST2H2BE; H3, including H3A1, particularly including HIST1H3A, HIST1H3B, HIST1H3C, HIST1H3D, HIST1H3E, HIST1H3F, HIST1H3G, HIST1H3H, HIST1H3I, HIST1H3J, and H3A2, particularly including HIST2H3C, and H3A3, particularly including HIST3H3; H4, including H41, particularly including HIST1H4A, HIST1H4B, HIST1H4C, HIST1H4D, HIST1H4E, HIST1H4F, HIST1H4G, HIST1H4H, HIST1H4I, HIST1H4J, HIST1H4K, HIST1H4L, and H44, particularly including HIST4H4, and H5.

According to the first aspect of the present invention, the inventive nucleic acid sequence comprises a coding region, encoding a peptide or protein which comprises a therapeutic protein or a fragment, variant or derivative thereof. Preferably, the encoded therapeutic protein is no reporter protein (e.g. Luciferase, Green Fluorescent Protein (GFP), Enhanced Green Fluorescent Protein (EGFP), β-Galactosidase) and no marker or selection protein (e.g. alpha-Globin, Galactokinase and Xanthine:guanine phosphoribosyl transferase (GPT)). Preferably, the nucleic acid sequence of the invention does not contain a (bacterial) antibiotics resistance gene, in particular not a neo gene sequence (Neomycin resistance gene) or CAT gene sequence (chloramphenicol acetyl transferase, chloramphenicol resistance gene).

The inventive nucleic acid as define above, comprises or codes for a) a coding region, encoding a peptide or protein which comprises a therapeutic protein or a fragment, variant or derivative thereof; b) at least one histone stem-loop, and c) a poly(A) sequence or polyadenylation signal; preferably for increasing the expression of said encoded peptide or protein, wherein the encoded peptide or protein is preferably no histone protein, no reporter protein and/or no marker or selection protein, as defined above. The elements b) to c) of the inventive nucleic acid may occur in the inventive nucleic acid in any order, i.e. the elements a), b) and c) may occur in the order a), b) and c) or a), c) and b) from 5′ to 3′ direction in the inventive nucleic acid sequence, wherein further elements as described herein, may also be contained, such as a 5′-CAP structure, a poly(C) sequence, stabilization sequences, IRES sequences, etc. Each of the elements a) to c) of the inventive nucleic acid, particularly a) in di- or multicistronic constructs and/or each of the elements b) and c), more preferably element b) may also be repeated at least once, preferably twice or more in the inventive nucleic acid. As an example, the inventive nucleic acid may show its sequence elements a), b) and optionally c) in e.g. the following order:

5′-coding region-histone stem-loop-poly(A) sequence-3′; or 5′-coding region-histone stem-loop-polyadenylation signal-3′; or 5′-coding region-poly(A) sequence-histone stem-loop-3′; or 5′-coding region-polyadenylation signal-histone stem-loop-3′; or 5′-coding region-coding region-histone stem-loop-polyadenylation signal-3′; or 5′-coding region-histone stem-loop-histone stem-loop-poly(A) sequence-3′; or 5′-coding region-histone stem-loop-histone stem-loop-polyadenylation signal-3′; etc.

In this context it is particularly preferred that the inventive nucleic acid sequence comprises or codes for a) a coding region, encoding a peptide or protein which comprises a therapeutic protein or fragment, variant or derivative thereof; b) at least one histone stem-loop, and c) a poly(A) sequence or polyadenylation sequence; preferably for increasing the expression level of said encoded peptide or protein, wherein the encoded protein is preferably no histone protein, no reporter protein (e.g. Luciferase, GFP, EGFP, β-Galactosidase, particularly EGFP) and/or no marker or selection protein (e.g. alpha-Globin, Galactokinase and Xanthine:Guanine phosphoribosyl transferase (GPT)).

In a further preferred embodiment of the first aspect the inventive nucleic acid sequence as defined herein may also occur in the form of a modified nucleic acid.

In this context, the inventive nucleic acid sequence as defined herein may be modified to provide a “stabilized nucleic acid”, preferably a stabilized RNA, more preferably an RNA that is essentially resistant to in vivo degradation (e.g. by an exo- or endo-nuclease). A stabilized nucleic acid may e.g. be obtained by modification of the G/C content of the coding region of the inventive nucleic acid sequence, by introduction of nucleotide analogues (e.g. nucleotides with backbone modifications, sugar modifications or base modifications) or by introduction of stabilization sequences in the 3′- and/or 5′-untranslated region of the inventive nucleic acid sequence.

As mentioned above, the inventive nucleic acid sequence as defined herein may contain nucleotide analogues/modifications e.g. backbone modifications, sugar modifications or base modifications. A backbone modification in connection with the present invention is a modification in which phosphates of the backbone of the nucleotides contained in inventive nucleic acid sequence as defined herein are chemically modified. A sugar modification in connection with the present invention is a chemical modification of the sugar of the nucleotides of the inventive nucleic acid sequence as defined herein. Furthermore, a base modification in connection with the present invention is a chemical modification of the base moiety of the nucleotides of the nucleic acid molecule of the inventive nucleic acid sequence. In this context nucleotide analogues or modifications are preferably selected from nucleotide analogues which are applicable for transcription and/or translation.

In a particular preferred embodiment of the first aspect of the present invention the herein defined nucleotide analogues/modifications are selected from base modifications which additionally increase the expression of the encoded protein and which are preferably selected from 2-amino-6-chloropurineriboside-5′-triphosphate, 2-aminoadenosine-5′-triphosphate, 2-thiocytidine-5′-triphosphate, 2-thiouridine-5′-triphosphate, 4-thiouridine-5′-triphosphate, 5-aminoallylcytidine-5′-triphosphate, 5-aminoallyluridine-5′-triphosphate, 5-bromocytidine-5′-triphosphate, 5-bromouridine-5′-triphosphate, 5-iodocytidine-5′-triphosphate, 5-iodouridine-5′-triphosphate, 5-methylcytidine-5′-triphosphate, 5-methyluridine-5′-triphosphate, 6-azacytidine-5′-triphosphate, 6-azauridine-5′-triphosphate, 6-chloropurineriboside-5′-triphosphate, 7-deazaadenosine-5′-triphosphate, 7-deazaguanosine-5′-triphosphate, 8-azaadenosine-5′-triphosphate, 8-azidoadenosine-5′-triphosphate, benzimidazole-riboside-5′-triphosphate, N1-methyladenosine-5′-triphosphate, N1-methylguanosine-5′-triphosphate, N6-methyladenosine-5′-triphosphate, 06-methylguanosine-5′-triphosphate, pseudouridine-5′-triphosphate, or puromycin-5′-triphosphate, xanthosine-5′-triphosphate. Particular preference is given to nucleotides for base modifications selected from the group of base-modified nucleotides consisting of 5-methylcytidine-5′-triphosphate, 7-deazaguanosine-5′-triphosphate, 5-bromocytidine-5′-triphosphate, and pseudouridine-5′-triphosphate.

According to a further embodiment, the inventive nucleic acid sequence as defined herein can contain a lipid modification. Such a lipid-modified nucleic acid typically comprises a nucleic acid as defined herein. Such a lipid-modified nucleic acid molecule of the inventive nucleic acid sequence as defined herein typically further comprises at least one linker covalently linked with that nucleic acid molecule, and at least one lipid covalently linked with the respective linker. Alternatively, the lipid-modified nucleic acid molecule comprises at least one nucleic acid molecule as defined herein and at least one (bifunctional) lipid covalently linked (without a linker) with that nucleic acid molecule. According to a third alternative, the lipid-modified nucleic acid molecule comprises a nucleic acid molecule as defined herein, at least one linker covalently linked with that nucleic acid molecule, and at least one lipid covalently linked with the respective linker, and also at least one (bifunctional) lipid covalently linked (without a linker) with that nucleic acid molecule. In this context it is particularly preferred that the lipid modification is present at the terminal ends of a linear inventive nucleic acid sequence.

According to another preferred embodiment of the first aspect of the invention, the inventive nucleic acid sequence as defined herein, particularly if provided as an (m)RNA, can therefore be stabilized against degradation by RNases by the addition of a so-called “5′ CAP” structure.

According to a further preferred embodiment of the first aspect of the invention, the inventive nucleic acid sequence as defined herein can be modified by a sequence of at least 10 cytidines, preferably at least 20 cytidines, more preferably at least 30 cytidines (so-called “poly(C) sequence”). Particularly, the inventive nucleic acid sequence may contain or code for a poly(C) sequence of typically about 10 to 200 cytidine nucleotides, preferably about 10 to 100 cytidine nucleotides, more preferably about 10 to 70 cytidine nucleotides or even more preferably about 20 to 50 or even 20 to 30 cytidine nucleotides. This poly(C) sequence is preferably located 3′ of the coding region comprised in the inventive nucleic acid according to the first aspect of the present invention.

In a particularly preferred embodiment of the present invention, the G/C content of the coding region, encoding at least one peptide or protein which comprises a therapeutic protein or a fragment, variant or derivative thereof of the inventive nucleic acid sequence as defined herein, is modified, particularly increased, compared to the G/C content of its particular wild type coding region, i.e. the unmodified coding region. The encoded amino acid sequence of the coding region is preferably not modified compared to the coded amino acid sequence of the particular wild type coding region.

The modification of the G/C-content of the coding region of the inventive nucleic acid sequence as defined herein is based on the fact that the sequence of any mRNA region to be translated is important for efficient translation of that mRNA. Thus, the composition and the sequence of various nucleotides are important. In particular, mRNA sequences having an increased G (guanosine)/C (cytosine) content are more stable than mRNA sequences having an increased A (adenosine)/U (uracil) content. According to the invention, the codons of the coding region are therefore varied compared to its wild type coding region, while retaining the translated amino acid sequence, such that they include an increased amount of G/C nucleotides. In respect to the fact that several codons code for one and the same amino acid (so-called degeneration of the genetic code), the most favourable codons for the stability can be determined (so-called alternative codon usage).

Depending on the amino acid to be encoded by the coding region of the inventive nucleic acid sequence as defined herein, there are various possibilities for modification of the nucleic acid sequence, e.g. the coding region, compared to its wild type coding region. In the case of amino acids which are encoded by codons which contain exclusively G or C nucleotides, no modification of the codon is necessary. Thus, the codons for Pro (CCC or CCG), Arg (CGC or CGG), Ala (GCC or GCG) and Gly (GGC or GGG) require no modification, since no A or U is present.

In contrast, codons which contain A and/or U nucleotides can be modified by substitution of other codons which code for the same amino acids but contain no A and/or U. Examples of these are:

the codons for Pro can be modified from CCU or CCA to CCC or CCG; the codons for Arg can be modified from CGU or CGA or AGA or AGG to CGC or CGG; the codons for Ala can be modified from GCU or GCA to GCC or GCG; the codons for Gly can be modified from GGU or GGA to GGC or GGG.

In other cases, although A or U nucleotides cannot be eliminated from the codons, it is however possible to decrease the A and U content by using codons which contain a lower content of A and/or U nucleotides. Examples of these are:

the codons for Phe can be modified from UUU to UUC; the codons for Leu can be modified from UUA, UUG, CUU or CUA to CUC or CUG; the codons for Ser can be modified from UCU or UCA or AGU to UCC, UCG or AGC; the codon for Tyr can be modified from UAU to UAC; the codon for Cys can be modified from UGU to UGC; the codon for His can be modified from CAU to CAC; the codon for Gln can be modified from CAA to CAG; the codons for Ile can be modified from AUU or AUA to AUC; the codons for Thr can be modified from ACU or ACA to ACC or ACG; the codon for Asn can be modified from AAU to AAC; the codon for Lys can be modified from AAA to AAG; the codons for Val can be modified from GUU or GUA to GUC or GUG; the codon for Asp can be modified from GAU to GAC; the codon for Glu can be modified from GAA to GAG; the stop codon UAA can be modified to UAG or UGA.

In the case of the codons for Met (AUG) and Trp (UGG), on the other hand, there is no possibility of sequence modification.

The substitutions listed above can be used either individually or in all possible combinations to increase the G/C content of the coding region of the inventive nucleic acid sequence as defined herein, compared to its particular wild type coding region (i.e. the original sequence). Thus, for example, all codons for Thr occurring in the wild type sequence can be modified to ACC (or ACG).

In the above context, codons present in mRNA are shown. Therefore uridine present in an mRNA may also be present as thymidine in the respective DNA coding for the particular mRNA.

Preferably, the G/C content of the coding region of the inventive nucleic acid sequence as defined herein is increased by at least 7%, more preferably by at least 15%, particularly preferably by at least 20%, compared to the G/C content of the wild type coding region. According to a specific embodiment at least 5%, 10%, 20%, 30%, 40%, 50%, 60%, more preferably at least 70%, even more preferably at least 80% and most preferably at least 90%, 95% or even 100% of the substitutable codons in the coding region encoding at least one peptide or protein which comprises a therapeutic protein or a fragment, variant or derivative thereof are substituted, thereby increasing the G/C content of said coding region.

In this context, it is particularly preferable to increase the G/C content of the coding region of the inventive nucleic acid sequence as defined herein, to the maximum (i.e. 100% of the substitutable codons), compared to the wild type coding region.

According to the invention, a further preferred modification of the coding region encoding at least one peptide or protein which comprises a therapeutic protein or a fragment, variant or derivative thereof of the inventive nucleic acid sequence as defined herein, is based on the finding that the translation efficiency is also determined by a different frequency in the occurrence of tRNAs in cells. Thus, if so-called “rare codons” are present in the coding region of the inventive nucleic acid sequence as defined herein, to an increased extent, the corresponding modified nucleic acid sequence is translated to a significantly poorer degree than in the case where codons coding for relatively “frequent” tRNAs are present.

In this context the coding region of the inventive nucleic acid sequence is preferably modified compared to the corresponding wild type coding region such that at least one codon of the wild type sequence which codes for a tRNA which is relatively rare in the cell is exchanged for a codon which codes for a tRNA which is relatively frequent in the cell and carries the same amino acid as the relatively rare tRNA. By this modification, the coding region of the inventive nucleic acid sequence as defined herein, is modified such that codons for which frequently occurring tRNAs are available are inserted. In other words, according to the invention, by this modification all codons of the wild type coding region which code for a tRNA which is relatively rare in the cell can in each case be exchanged for a codon which codes for a tRNA which is relatively frequent in the cell and which, in each case, carries the same amino acid as the relatively rare tRNA.

Which tRNAs occur relatively frequently in the cell and which, in contrast, occur relatively rarely is known to a person skilled in the art; cf. e.g. Akashi, Curr. Opin. Genet. Dev. 2001, 11(6): 660-666. The codons which use for the particular amino acid the tRNA which occurs the most frequently, e.g. the Gly codon, which uses the tRNA which occurs the most frequently in the (human) cell, are particularly preferred.

According to the invention, it is particularly preferable to link the sequential G/C content which is increased, in particular maximized, in the coding region of the inventive nucleic acid sequence as defined herein, with the “frequent” codons without modifying the amino acid sequence of the peptide or protein encoded by the coding region of the nucleic acid sequence. This preferred embodiment allows provision of a particularly efficiently translated and stabilized (modified) inventive nucleic acid sequence as defined herein.

According to another preferred embodiment of the first aspect of the invention, the inventive nucleic acid sequence as defined herein, preferably has additionally at least one 5′ and/or 3′ stabilizing sequence. These stabilizing sequences in the 5′ and/or 3′ untranslated regions have the effect of increasing the half-life of the nucleic acid, particularly of the mRNA in the cytosol. These stabilizing sequences can have 100% sequence identity to naturally occurring sequences which occur in viruses, bacteria and eukaryotes, but can also be partly or completely synthetic. The untranslated sequences (UTR) of the (alpha-)globin gene, e.g. from Homo sapiens or Xenopus laevis may be mentioned as an example of stabilizing sequences which can be used in the present invention for a stabilized nucleic acid. Another example of a stabilizing sequence has the general formula (C/U)CCAN_(x)CCC(U/A)Py_(x)UC(C/U)CC (SEQ ID NO: 55), which is contained in the 3′-UTRs of the very stable RNAs which code for (alpha-)globin, type(I)-collagen, 15-lipoxygenase or for tyrosine hydroxylase (cf. Holcik et al., Proc. Natl. Acad. Sci. USA 1997, 94: 2410 to 2414). Such stabilizing sequences can of course be used individually or in combination with one another and also in combination with other stabilizing sequences known to a person skilled in the art. In this context it is particularly preferred that the 3′ UTR sequence of the alpha globin gene is located 3′ of the coding region encoding at least one peptide or protein which comprises a therapeutic protein or a fragment, variant or derivative thereof comprised in the inventive nucleic acid sequence according to the first aspect of the present invention.

Substitutions, additions or eliminations of bases are preferably carried out with the inventive nucleic acid sequence as defined herein, using a DNA matrix for preparation of the nucleic acid sequence by techniques of the well-known site directed mutagenesis or with an oligonucleotide ligation strategy (see e.g. Maniatis et al., Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory Press, 3rd ed., Cold Spring Harbor, N.Y., 2001).

Any of the above modifications may be applied to the inventive nucleic acid sequence as defined herein and further to any nucleic acid as used in the context of the present invention and may be, if suitable or necessary, be combined with each other in any combination, provided, these combinations of modifications do not interfere with each other in the respective nucleic acid. A person skilled in the art will be able to take his choice accordingly.

Nucleic acid sequences used according to the present invention as defined herein may be prepared using any method known in the art, including synthetic methods such as e.g. solid phase synthesis, as well as in vitro methods, such as in vitro transcription reactions or in vivo reactions, such as in vivo propagation of DNA plasmids in bacteria.

In such a process, for preparation of the inventive nucleic acid sequence as defined herein, especially if the nucleic acid is in the form of an mRNA, a corresponding DNA molecule may be transcribed in vitro. This DNA matrix preferably comprises a suitable promoter, e.g. a T7 or SP6 promoter, for in vitro transcription, which is followed by the desired nucleotide sequence for the nucleic acid molecule, e.g. mRNA, to be prepared and a termination signal for in vitro transcription. The DNA molecule, which forms the matrix of the at least one RNA of interest, may be prepared by fermentative proliferation and subsequent isolation as part of a plasmid which can be replicated in bacteria.

The inventive nucleic acid sequence as defined herein as well as proteins or peptides as encoded by this nucleic acid sequence may comprise fragments or variants of those sequences. Such fragments or variants may typically comprise a sequence having a sequence identity with one of the above mentioned nucleic acids, or with one of the proteins or peptides or sequences, if encoded by the inventive nucleic acid sequence, of at least 5%, 10%, 20%, 30%, 40%, 50%, 60%, preferably at least 70%, more preferably at least 80%, equally more preferably at least 85%, even more preferably at least 90% and most preferably at least 95% or even 97%, 98% or 99%, to the entire wild type sequence, either on nucleic acid level or on amino acid level.

“Fragments” of proteins or peptides in the context of the present invention (e.g. as encoded by the inventive nucleic acid sequence as defined herein) may comprise a sequence of a protein or peptide as defined herein, which is, with regard to its amino acid sequence (or its encoded nucleic acid molecule), N-terminally, C-terminally and/or intrasequentially truncated/shortened compared to the amino acid sequence of the original (native) protein (or its encoded nucleic acid molecule). Such truncation may thus occur either on the amino acid level or correspondingly on the nucleic acid level. A sequence identity with respect to such a fragment as defined herein may therefore preferably refer to the entire protein or peptide as defined herein or to the entire (coding) nucleic acid molecule of such a protein or peptide. Likewise, “fragments” of nucleic acids in the context of the present invention may comprise a sequence of a nucleic acid as defined herein, which is, with regard to its nucleic acid molecule 5′-, 3′- and/or intrasequentially truncated/shortened compared to the nucleic acid molecule of the original (native) nucleic acid molecule. A sequence identity with respect to a fragment as defined herein may therefore preferably refer to the entire nucleic acid as defined herein and the preferred sequence identity level typically is as indicated herein. Fragments have the same biological function or specific activity or at least retain an activity of the natural full length protein of at least 50%, more preferably at least 70%, even more preferably at least 90% (measured in an appropriate functional assay, e.g. an assay assessing the enzymatic activity of the fragment of the therapeutic protein or the binding activity thereof) as compared to the full-length native wt peptide or protein, e.g. its specific antigenic or therapeutic property. Accordingly, in a preferred embodiment, the “fragment” is a portion of the full-length (naturally occurring) wt therapeutic protein, which exerts therapeutic properties as indicated herein.

Furthermore also domains of a protein, like the extracellular domain, the intracellular domain or the transmembrane domain and shortened or truncated versions of a protein may be understood to comprise/correspond to a fragment of a protein.

“Variants” of proteins or peptides as defined in the context of the present invention may be encoded by the inventive nucleic acid sequence as defined herein. Thereby, a protein or peptide may be generated, having an amino acid sequence which differs from the original sequence in one or more (2, 3, 4, 5, 6, 7 or more) mutation(s), such as one or more substituted, inserted and/or deleted amino acid(s). The preferred level of sequence identity of “variants” in view of the full-length natural wt protein sequence typically is as indicated herein. Preferably, variants have the same biological function or specific activity or at least retain an activity of the natural full length protein of at least 50%, more preferably at least 70%, even more preferably at least 90% (measured in an appropriate functional assay, e.g. an assay assessing the enzymatic activity of the variant of the therapeutic protein or the binding activity thereof) as compared to the full-length native peptide or protein, e.g. its specific therapeutic property. Accordingly, in a preferred embodiment, the “variant” is a variant of a therapeutic protein, which exerts therapeutic properties to the extent as indicated herein.

“Variants” of proteins or peptides as defined in the context of the present invention (e.g. as encoded by a nucleic acid as defined herein) may comprise conservative amino acid substitution(s) compared to their native, i.e. non-mutated physiological, sequence. Those amino acid sequences as well as their encoding nucleotide sequences in particular fall under the term variants as defined herein. Substitutions in which amino acids, which originate from the same class, are exchanged for one another are called conservative substitutions. In particular, these are amino acids having aliphatic side chains, positively or negatively charged side chains, aromatic groups in the side chains or amino acids, the side chains of which can enter into hydrogen bridges, e.g. side chains which have a hydroxyl function. This means that e.g. an amino acid having a polar side chain is replaced by another amino acid having a likewise polar side chain, or, for example, an amino acid characterized by a hydrophobic side chain is substituted by another amino acid having a likewise hydrophobic side chain (e.g. serine (threonine) by threonine (serine) or leucine (isoleucine) by isoleucine (leucine)). Insertions and substitutions are possible, in particular, at those sequence positions which cause no modification to the three-dimensional structure or do not affect the binding region. Modifications to a three-dimensional structure by insertion(s) or deletion(s) can easily be determined e.g. using CD spectra (circular dichroism spectra) (Urry, 1985, Absorption, Circular Dichroism and ORD of Polypeptides, in: Modern Physical Methods in Biochemistry, Neuberger et al. (ed.), Elsevier, Amsterdam).

Furthermore, variants of proteins or peptides as defined herein, which may be encoded by the inventive nucleic acid sequence as defined herein, may also comprise those sequences, wherein nucleotides of the nucleic acid are exchanged according to the degeneration of the genetic code, without leading to an alteration of the respective amino acid sequence of the protein or peptide, i.e. the amino acid sequence or at least part thereof may not differ from the original sequence in one or more mutation(s) within the above meaning.

In order to determine the percentage to which two sequences are identical, e.g. nucleic acid sequences or amino acid sequences as defined herein, preferably the amino acid sequences encoded by the inventive nucleic acid sequence as defined herein or the amino acid sequences themselves, the sequences can be aligned in order to be subsequently compared to one another. Therefore, e.g. a position of a first sequence may be compared with the corresponding position of the second sequence. If a position in the first sequence is occupied by the same component as is the case at a position in the second sequence, the two sequences are identical at this position. If this is not the case, the sequences differ at this position. If insertions occur in the second sequence in comparison to the first sequence, gaps can be inserted into the first sequence to allow a further alignment. If deletions occur in the second sequence in comparison to the first sequence, gaps can be inserted into the second sequence to allow a further alignment. The percentage to which two sequences are identical is then a function of the number of identical positions divided by the total number of positions including those positions which are only occupied in one sequence. The percentage to which two sequences are identical can be determined using a mathematical algorithm. A preferred, but not limiting, example of a mathematical algorithm which can be used is the algorithm of Karlin et al. (1993), PNAS USA, 90:5873-5877 or Altschul et al. (1997), Nucleic Acids Res., 25:3389-3402. Such an algorithm is integrated in the BLAST program. Sequences which are identical to the sequences of the present invention to a certain extent can be identified by this program.

The inventive nucleic acid sequence as defined herein may encode derivatives of a peptide or protein. Such a derivative of a peptide or protein is a molecule that is derived from another molecule, such as said peptide or protein. A “derivative” typically contains the full-length sequence of the natural wt peptide or protein and additional sequence features, e.g. at the N- or at the C-terminus, which may exhibit an additional function to the natural full-length peptide/protein. Again such derivatives have the same biological function or specific activity or at least retain an activity of the natural wt full-length protein of at least 50%, more preferably at least 70%, even more preferably at least 90% (measured in an appropriate functional assay, see above, e.g. a binding or an enzyme activity assay) as compared to the full-length native peptide or protein, e.g. its specific therapeutic property. Thereby, a “derivative” of a peptide or protein also encompasses (chimeric) fusion peptides/proteins comprising a peptide or protein used in the present invention or a natural full-length protein (or variant/fragment thereof) fused to a distinct peptide/protein awarding e.g. two or more biological functions to the fusion peptide/protein. For example, the fusion may comprise a label, such as, for example, an epitope, e.g., a FLAG epitope or a V5 epitope or an HA epitope. For example, the epitope is a FLAG epitope. Such a tag is useful for, for example, purifying the fusion protein.

In this context, a “variant” of a protein or peptide may have at least 70%, 75%, 80%, 85%, 90%, 95%, 98% or 99% amino acid identity over a stretch of 10, 20, 30, 50, 75 or 100 amino acids of such protein or peptide. Analogously, a “variant” of a nucleic acid sequence, or particularly, a fragment, may have at least 70%, 75%, 80%, 85%, 90%, 95%, 98% or 99% nucleotide identity over a stretch of 10, 20, 30, 50, 75 or 100 nucleotide of such nucleic acid sequence; typically, however, referring to the naturally occurring full-length sequences. In case of “fragments” typically, sequence identity is determined for the fragment over the length (of the fragment) on the portion of the full-length protein (reflecting the same length as the fragment), which exhibits the highest level of sequence identity.

In this context it is particularly preferred that the inventive nucleic acid is complexed at least partially with a cationic or polycationic compound, preferably cationic proteins or peptides. Partially means that only a part of the inventive nucleic acid is complexed with a cationic or polycationic compound and that the rest of the inventive nucleic acid is in uncomplexed form (“free”). Preferably the ratio of complexed nucleic acid to:free nucleic acid is selected from a range. of about 5:1 (w/w) to about 1:10 (w/w), more preferably from a range of about 4:1 (w/w) to about 1:8 (w/w), even more preferably from a range of about 3:1 (w/w) to about 1:5 (w/w) or 1:3 (w/w), and most preferably the ratio of complexed nucleic acid to free nucleic acid is selected from a ratio of about 1:1 (w/w).

Accordingly, in a particular preferred aspect, the present invention also provides a pharmaceutical composition, comprising an inventive nucleic acid as defined herein or an inventive composition comprising a plurality of inventive nucleic acid sequences as defined herein and optionally a pharmaceutically acceptable carrier and/or vehicle.

Reference media are e.g. liquids occurring in “in vivo” methods, such as blood, lymph, cytosolic liquids, or other body liquids, or e.g. liquids, which may be used as reference media in “in vitro” methods, such as common buffers or liquids. Such common buffers or liquids are known to a skilled person. Ringer-Lactate solution is particularly preferred as a liquid basis.

However, one or more compatible solid or liquid fillers or diluents or encapsulating compounds may be used as well for the inventive pharmaceutical composition, which are suitable for administration to a patient to be treated. The term “compatible” as used here means that these constituents of the inventive pharmaceutical composition are capable of being mixed with the inventive nucleic acid as defined herein in such a manner that no interaction occurs which would substantially reduce the pharmaceutical effectiveness of the inventive pharmaceutical composition under typical use conditions.

According to a specific embodiment, the inventive pharmaceutical composition may comprise an adjuvant. In this context, an adjuvant may be understood as any compound, which is suitable to initiate or increase an immune response of the innate immune system, i.e. a non-specific immune response. With other words, when administered, the inventive pharmaceutical composition preferably elicits an innate immune response due to the adjuvant, optionally contained therein.

Particularly preferred is intradermal and intramuscular injection. Sterile injectable forms of the inventive pharmaceutical compositions may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents.

The inventive pharmaceutical composition as defined herein may also be administered orally in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions.

The inventive pharmaceutical composition may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, e.g. including diseases of the skin or of any other accessible epithelial tissue. Suitable topical formulations are readily prepared for each of these areas or organs. For topical applications, the inventive pharmaceutical composition may be formulated in a suitable ointment, containing the inventive nucleic acid as defined herein suspended or dissolved in one or more carriers.

The inventive pharmaceutical composition typically comprises a “safe and effective amount” of the components of the inventive pharmaceutical composition, particularly of the inventive nucleic acid sequence(s) as defined herein. As used herein, a “safe and effective amount” means an amount of the inventive nucleic acid sequence(s) as defined herein as such that is sufficient to significantly induce a positive modification of a disease or disorder as defined herein. At the same time, however, a “safe and effective amount” is small enough to avoid serious side-effects and to permit a sensible relationship between advantage and risk. The determination of these limits typically lies within the scope of sensible medical judgment.

FIG. 17: shows ppLuc(GC)-ag-A64-N32 (SEQ ID NO: 54)

-   -   By linearization of the original vector at an alternative         restriction site, mRNA is obtained with 32 additional         nucleotides following poly(A).

FIG. 18: shows the mRNA sequence of MmEPO (GC)-ag-A64-C30 (SEQ ID NO: 55)

FIG. 19: shows the mRNA sequence of MmEPO (GC)-ag-A64-C30-histoneSL (SEQ ID NO: 56)

FIG. 20: shows that the combination of poly(A) and histoneSL increases protein expression from mRNA in a synergistic manner.

-   -   The effect of poly(A) sequence, histoneSL, and the combination         of poly(A) and histoneSL on luciferase expression from mRNA was         examined. Therefore different mRNAs were electroporated into         HeLa cells. Luciferase levels were measured at 6, 24, and 48         hours after transfection. Little luciferase is expressed from         mRNA having neither poly(A) sequence nor histoneSL. Both a         poly(A) sequence or the histoneSL increase the luciferase level.         Strikingly however, the combination of poly(A) and histoneSL         further strongly increases the luciferase level, manifold above         the level observed with either of the individual elements, thus         acting synergistically. Data are graphed as mean RLU±SD         (relative light units±standard deviation) for triplicate         transfections. Specific RLU are summarized in Example 10.2.

FIG. 21: shows that the combination of poly(A) and histoneSL increases protein expression from mRNA irrespective of their order.

-   -   The effect of poly(A) sequence, histoneSL, the combination of         poly(A) and histoneSL, and their order on luciferase expression         from mRNA was examined. Therefore different mRNAs were         lipofected into HeLa cells. Luciferase levels were measured at         6, 24, and 48 hours after the start of transfection. Both an A64         poly(A) sequence or the histoneSL give rise to comparable         luciferase levels. Increasing the length of the poly(A) sequence         from A64 to A120 or to A300 increases the luciferase level         moderately. In contrast, the combination of poly(A) and         histoneSL increases the luciferase level much further than         lengthening of the poly(A) sequence. The combination of poly(A)         and histoneSL acts synergistically as it increases the         luciferase level manifold above the level observed with either         of the individual elements. The synergistic effect of the         combination of poly(A) and histoneSL is seen irrespective of the         order of poly(A) and histoneSL and irrespective of the length of         poly(A) with A64-histoneSL or histoneSL-A250 mRNA. Data are         graphed as mean RLU±SD for triplicate transfections. Specific         RLU are summarized in Example 10.3.

FIG. 22: shows that the rise in protein expression by the combination of poly(A) and histoneSL is specific.

-   -   The effect of combining poly(A) and histoneSL or poly(A) and         alternative sequences on luciferase expression from mRNA was         examined. Therefore different mRNAs were electroporated into         HeLa cells. Luciferase levels were measured at 6, 24, and 48         hours after transfection. Both a poly(A) sequence or the         histoneSL give rise to comparable luciferase levels. The         combination of poly(A) and histoneSL strongly increases the         luciferase level, manifold above the level observed with either         of the individual elements, thus acting synergistically. In         contrast, combining poly(A) with any of the other sequences is         without effect on the luciferase level compared to mRNA         containing only a poly(A) sequence. Thus, the combination of         poly(A) and histoneSL acts specifically and synergistically.         Data are graphed as mean RLU±SD for triplicate transfections.         Specific RLU are summarized in Example 10.4.

FIG. 23: shows that the combination of poly(A) and histoneSL increases protein expression from mRNA in a synergistic manner in vivo.

-   -   The effect of poly(A) sequence, histoneSL, and the combination         of poly(A) and histoneSL on luciferase expression from mRNA in         vivo was examined. Therefore different mRNAs were injected         intradermally into mice. Mice were sacrificed 16 hours after         injection and Luciferase levels at the injection sites were         measured. Luciferase is expressed from mRNA having either a         histoneSL or a poly(A) sequence. Strikingly however, the         combination of poly(A) and histoneSL strongly increases the         luciferase level, manifold above the level observed with either         of the individual elements, thus acting synergistically. Data         are graphed as mean RLU±SEM (relative light units±standard error         of mean). Specific RLU are summarized in Example 10.5.

FIG. 24: shows the mRNA sequence of Trastuzumab (GC)-ag-A64-C30 (SEQ ID NO: 57). This sequence encodes the antibody Trastuzumab (Herceptin) comprising the light and heavy chains as described in WO2008/083949.

FIG. 25: shows the mRNA sequence of Trastuzumab (GC)-ag-A64-C30-histoneSL (SEQ ID NO: 58). This sequence encodes the antibody Trastuzumab (Herceptin) comprising the light and heavy chains as described in WO2008/083949.

EXAMPLES

The following Examples are intended to illustrate the invention further and shall not be construed to limit the present invention thereto.

1. Generation of Histone-Stem-Loop Consensus Sequences

-   -   Prior to the experiments, histone stem-loop consensus sequences         were determined on the basis of metazoan and protozoan histone         stem-loop sequences. Sequences were taken from the supplement         provided by Lopez et al. (Dávila López, M., & Samuelsson, T.         (2008), RNA (New York, N.Y.), 14(1), 1-10.         doi:10.1261/rna.782308), who identified a large number of         natural histone stem-loop sequences by searching genomic         sequences and expressed sequence tags. First, all sequences from         metazoa and protozoa (4001 sequences), or all sequences from         protozoa (131 sequences) or alternatively from metazoa (3870         sequences), or from vertebrates (1333 sequences) or from humans         (84 sequences) were grouped and aligned. Then, the quantity of         the occurring nucleotides was determined for every position.         Based on the tables thus obtained, consensus sequences for the 5         different groups of sequences were generated representing all         nucleotides present in the sequences analyzed. In addition, more         restrictive consensus sequences were also obtained, increasingly         emphasizing conserved nucleotides

2. Preparation of DNA-Templates

-   -   A vector for in vitro transcription was constructed containing a         T7 promoter followed by a GC-enriched sequence coding for         Photinus pyralis luciferase (ppLuc(GC)), the center part of the         3′ untranslated region (UTR) of alpha-globin (ag), and a poly(A)         sequence. The poly(A) sequence was immediately followed by a         restriction site used for linearization of the vector before in         vitro transcription in order to obtain mRNA ending in an A64         poly(A) sequence. mRNA obtained from this vector accordingly by         in vitro transcription is designated as “ppLuc(GC)-ag-A64”.     -   Linearization of this vector at alternative restriction sites         before in vitro transcription allowed to obtain mRNA either         extended by additional nucleotides 3′ of A64 or lacking A64. In         addition, the original vector was modified to include         alternative sequences. In summary, the following mRNAs were         obtained from these vectors by in vitro transcription (mRNA         sequences are given in FIGS. 6 to 17):

(SEQ ID NO: 43) ppLuc(GC)-ag (SEQ ID NO: 44) ppLuc(GC)-ag-A64 (SEQ ID NO: 45) ppLuc(GC)-ag-histoneSL (SEQ ID NO: 46) ppLuc(GC)-ag-A64-histoneSL (SEQ ID NO: 47) ppLuc(GC)-ag-A120 (SEQ ID NO: 48) ppLuc(GC)-ag-A64-ag (SEQ ID NO: 49) ppLuc(GC)-ag-A64-aCPSL (SEQ ID NO: 50) ppLuc(GC)-ag-A64-PolioCL (SEQ ID NO: 51) ppLuc(GC)-ag-A64-G30 (SEQ ID NO: 52) ppLuc(GC)-ag-A64-U30 (SEQ ID NO: 53) ppLuc(GC)-ag-A64-SL (SEQ ID NO: 54) ppLuc(GC)-ag-A64-N32

-   -   Furthermore DNA plasmid sequences coding for the therapeutic         protein EPO was prepared accordingly as described above.     -   In summary, the following mRNAs were obtained from these vectors         by in vitro transcription (mRNA sequences are given in FIGS. 18         to 19):

(SEQ ID NO: 55) MmEPO (GC)-ag-A64-C30 (SEQ ID NO: 56) MmEPO (GC)-ag-A64-C30-histoneSL

-   -   Furthermore DNA plasmid sequences coding for the antibody         Trastuzumab can be prepared accordingly as described above.     -   The following mRNAs are obtained from these vectors by in vitro         transcription (mRNA sequences are given in FIGS. 24 and 25):

(SEQ ID NO: 57) Trastuzumab (GC)-ag-A64-C30 (SEQ ID NO: 58) Trastuzumab (GC)-ag-A6-C30-histoneSL

3. In Vitro Transcription

-   -   The DNA-template according to Example 2 was linearized and         transcribed in vitro using T7-Polymerase. The DNA-template was         then digested by DNase-treatment. All mRNA-transcripts contained         a 5′-CAP structure obtained by adding an excess of         N7-Methyl-Guanosine-5′-Triphosphate-5′-Guanosine to the         transcription reaction. mRNA thus obtained was purified and         resuspended in water.         4. Enzymatic Adenylation of mRNA     -   Two mRNAs were enzymatically adenylated:     -   ppLuc(GC)-ag-A64 and ppLuc(GC)-ag-histoneSL.     -   To this end, RNA was incubated with E. coli Poly(A)-polymerase         and ATP (Poly(A) Polymerase Tailing Kit, Epicentre, Madison,         USA) following the manufacturer's instructions. mRNA with         extended poly(A) sequence was purified and resuspended in water.         The length of the poly(A) sequence was determined via agarose         gel electrophoresis. Starting mRNAs were extended by         approximately 250 adenylates, the mRNAs obtained are designated         as     -   ppLuc(GC)-ag-A300 and ppLuc(GC)-ag-histoneSL-A250, respectively.         5. Luciferase Expression by mRNA Electroporation     -   HeLa cells were trypsinized and washed in OPTI-MEM®. 1×10⁵ cells         in 200 μl of opti-MEM each were electroporated with 0.5 μg of         ppLuc-encoding mRNA. As a control, mRNA not coding for ppLuc was         electroporated separately. Electroporated cells were seeded in         24-well plates in 1 ml of RPMI 1640 medium. 6, 24, or 48 hours         after transfection, medium was aspirated and cells were lysed in         200 μl of lysis buffer (25 mM Tris, pH 7.5 (HCl), 2 mM EDTA, 10%         glycerol, 1% Triton X-100, 2 mM DTT, 1 mM PMSF). Lysates were         stored at −20° C. until ppLuc activity was measured.         6. Luciferase Expression by mRNA Lipofection     -   HeLa cells were seeded in 96 well plates at a density of 2×10⁴         cells per well. The following day, cells were washed in         OPTI-MEM® and then transfected with 0.25 μg of         Lipofectin-complexed ppLuc-encoding mRNA in 150 μl of OPTI-MEM®.         As a control, mRNA not coding for ppLuc was lipofected         separately. In some wells, OPTI-MEM® was aspirated and cells         were lysed in 200 μl of lysis buffer 6 hours after the start of         transfection. In the remaining wells, OPTI-MEM® was exchanged         for RPMI 1640 medium at that time. In these wells, medium was         aspirated and cells were lysed in 200 μl of lysis buffer 24 or         48 hours after the start of transfection. Lysates were stored at         −20° C. until ppLuc activity was measured.

7. Luciferase Measurement

-   -   ppLuc activity was measured as relative light units (RLU) in a         BioTek SYNERGY™ HT plate reader at 5 seconds measuring time         using 50 μl of lysate and 200 μl of luciferin buffer (25 mM         Glycylglycin, pH 7.8 (NaOH), 15 mM MgSO₄, 2 mM ATP, 75 μM         luciferin). Specific RLU were calculated by subtracting RLU of         the control RNA from total RLU.         8. Luciferase Expression by Intradermal mRNA Injection         (Luciferase Expression in Vivo)     -   Mice were anaesthetized with a mixture of ROMPUN™ and KETAVET™.         Each ppLuc-encoding mRNA was injected intradermally (0.5 μg of         mRNA in 50 μl per injection). As a control, mRNA not coding for         ppLuc was injected separately. 16 hours after injection, mice         were sacrificed and tissue collected. Tissue samples were flash         frozen in liquid nitrogen and lysed in a tissue lyser (Qiagen)         in 800 μl of lysis buffer (25 mM Tris, pH 7.5 (HCl), 2 mM EDTA,         10% glycerol, 1% Triton X-100, 2 mM DTT, 1 mM PMSF).         Subsequently samples were centrifuged at 13500 rpm at 4° C. for         10 minutes. Lysates were stored at −80° C. until ppLuc activity         was measured (see 7. luciferase measurement).

9. MmEPO Expression in HeLa Cells

-   -   HeLa cells are trypsinized and washed in OPTI-MEM®. 1×10⁵ cells         in 200 μl of OPTI-MEM® each are electroporated with 0.5 μg of         MmEPO-encoding mRNA. As a control, irrelevant mRNA is         electroporated separately. Electroporated cells are seeded in         24-well plates in 1 ml of RPMI 1640 medium. 6, 24, or 48 hours         after transfection, supernatants are taken and harvested from         the cells. The content of EPO in the supernatants is measured         with the Mouse/Rat Erythropoietin QUANTIKINE® ELISA Kit (R&D         Systems) according to the manufacturer's instructions.

10. Results 10.1 Histone Stem-Loop Sequences:

-   -   In order to characterize histone stem-loop sequences, sequences         from metazoa and protozoa (4001 sequences), or from protozoa         (131 sequences) or alternatively from metazoa (3870 sequences),         or from vertebrates (1333 sequences) or from humans (84         sequences) were grouped and aligned. Then, the quantity of the         occurring nucleotides was determined for every position. Based         on the tables thus obtained, consensus sequences for the 5         different groups of sequences were generated representing all         nucleotides present in the sequences analyzed. Within the         consensus sequence of metazoa and protozoa combined, 3         nucleotides are conserved, a T/U in the loop and a G and a C in         the stem, forming a base pair. Structurally, typically a 6         base-pair stem and a loop of 4 nucleotides is formed. However,         deviating structures are common: Of 84 human histone stem-loops,         two contain a stem of only 5 nucleotides comprising 4 base-pairs         and one mismatch. Another human histone stem-loop contains a         stem of only 5 base-pairs. Four more human histone stem-loops         contain a 6 nucleotide long stem, but include one mismatch at         three different positions, respectively. Furthermore, four human         histone stem-loops contain one wobble base-pair at two different         positions, respectively. Concerning the loop, a length of 4         nucleotides seems not to be strictly required, as a loop of 5         nucleotides has been identified in D. discoideum.     -   In addition to the consensus sequences representing all         nucleotides present in the sequences analyzed, more restrictive         consensus sequences were also obtained, increasingly emphasizing         conserved nucleotides.

-   -   To investigate the effect of the combination of poly(A) and         histoneSL on protein expression from mRNA, mRNAs with different         sequences 3′ of the alpha-globin 3′-UTR were synthesized: mRNAs         either ended just 3′ of the 3′-UTR, thus lacking both poly(A)         sequence and histoneSL, or contained either an A64 poly(A)         sequence or a histoneSL instead, or both A64 poly(A) and         histoneSL 3′ of the 3′-UTR. Luciferase-encoding mRNAs or control         mRNA were electroporated into HeLa cells. Luciferase levels were         measured at 6, 24, and 48 hours after transfection (see         following Table 6 and FIG. 20).

TABLE 6 RLU at RLU at RLU at mRNA 6 hours 24 hours 48 hours ppLuc(GC)-ag-A64- 466553 375169 70735 histoneSL ppLuc(GC)-ag-histoneSL 50947 3022 84 ppLuc(GC)-ag-A64 10471 19529 4364 ppLuc(GC)-ag 997 217 42

-   -   Little luciferase was expressed from mRNA having neither poly(A)         sequence nor histoneSL. Both a poly(A) sequence or the histoneSL         increased the luciferase level to a similar extent. Either mRNA         gave rise to a luciferase level much higher than did mRNA         lacking both poly(A) and histoneSL. Strikingly however, the         combination of poly(A) and histoneSL further strongly increased         the luciferase level, manifold above the level observed with         either of the individual elements. The magnitude of the rise in         luciferase level due to combining poly(A) and histoneSL in the         same mRNA demonstrates that they are acting synergistically.     -   The synergy between poly(A) and histoneSL was quantified by         dividing the signal from poly(A)-histoneSL mRNA (+/+) by the sum         of the signals from histoneSL mRNA (−/+) plus poly(A) mRNA (+/−)         (see following Table 7).

TABLE 7 RLU at RLU at RLU at A64 histoneSL 6 hours 24 hours 48 hours + + 466553 375169 70735 − + 50947 3022 84 + − 10471 19529 4364 Synergy 7.6 16.6 15.9

-   -   The factor thus calculated specifies how much higher the         luciferase level from mRNA combining poly(A) and histoneSL is         than would be expected if the effects of poly(A) and histoneSL         were purely additive. The luciferase level from mRNA combining         poly(A) and histoneSL was up to 16.6 times higher than if their         effects were purely additive. This result confirms that the         combination of poly(A) and histoneSL effects a markedly         synergistic increase in protein expression.         10.3 the Combination of Poly(A) and histoneSL Increases Protein         Expression from mRNA Irrespective of their Order.     -   The effect of the combination of poly(A) and histoneSL might         depend on the length of the poly(A) sequence and the order of         poly(A) and histoneSL. Thus, mRNAs with increasing poly(A)         sequence length and mRNA with poly(A) and histoneSL in reversed         order were synthesized: Two mRNAs contained 3′ of the 3′-UTR         either an A120 or an A300 poly(A) sequence. One further mRNA         contained 3′ of the 3′-UTR first a histoneSL followed by an A250         poly(A) sequence. Luciferase-encoding mRNAs or control mRNA were         lipofected into HeLa cells. Luciferase levels were measured at         6, 24, and 48 hours after the start of transfection (see         following Table 8 and FIG. 21).

-   -   Both an A64 poly(A) sequence or the histoneSL gave rise to         comparable luciferase levels. In agreement with the previous         experiment did the combination of A64 and histoneSL strongly         increase the luciferase level, manifold above the level observed         with either of the individual elements. The magnitude of the         rise in luciferase level due to combining poly(A) and histoneSL         in the same mRNA demonstrates that they are acting         synergistically. The synergy between A64 and histoneSL was         quantified as before based on the luciferase levels of         A64-histoneSL, A64, and histoneSL mRNA (see following Table 9).         The luciferase level from mRNA combining A64 and histoneSL was         up to 61.7 times higher than if the effects of poly(A) and         histoneSL were purely additive.

-   -   In contrast, increasing the length of the poly(A) sequence from         A64 to A120 or to A300 increased the luciferase level only         moderately (see Table 8 and FIG. 19). mRNA with the longest         poly(A) sequence, A300, was also compared to mRNA in which a         poly(A) sequence of similar length was combined with the         histoneSL, histoneSL-A250. In addition to having a long poly(A)         sequence, the order of histoneSL and poly(A) is reversed in this         mRNA relative to A64-histoneSL mRNA. The combination of A250 and         histoneSL strongly increased the luciferase level, manifold         above the level observed with either histoneSL or A300. Again,         the synergy between A250 and histoneSL was quantified as before         comparing RLU from histoneSL-A250 mRNA to RLU from A300 mRNA         plus histoneSL mRNA (see following Table 10). The luciferase         level from mRNA combining A250 and histoneSL was up to 17.0         times higher than if the effects of poly(A) and histoneSL were         purely additive.

-   -   In summary, a highly synergistic effect of the combination of         histoneSL and poly(A) on protein expression from mRNA has been         demonstrated for substantially different lengths of poly(A) and         irrespective of the order of poly(A) and histoneSL.         10.4 the Rise in Protein Expression by the Combination of         Poly(A) and histoneSL is Specific     -   To investigate whether the effect of the combination of poly(A)         and histoneSL on protein expression from mRNA is specific, mRNAs         with alternative sequences in combination with poly(A) were         synthesized: These mRNAs contained 3′ of A64 one of seven         distinct sequences, respectively. Luciferase-encoding mRNAs or         control mRNA were electroporated into HeLa cells. Luciferase         levels were measured at 6, 24, and 48 hours after transfection         (see following Table 11 and FIG. 22).

-   -   Both a poly(A) sequence or the histoneSL gave rise to comparable         luciferase levels. Again, the combination of poly(A) and         histoneSL strongly increased the luciferase level, manifold         above the level observed with either of the individual elements,         thus acting synergistically. In contrast, combining poly(A) with         any of the alternative sequences was without effect on the         luciferase level compared to mRNA containing only a poly(A)         sequence. Thus, the combination of poly(A) and histoneSL         increases protein expression from mRNA in a synergistic manner,         and this effect is specific.         10.5 the Combination of Poly(A) and histoneSL Increases Protein         Expression from mRNA in a Synergistic Manner In Vivo.     -   To investigate the effect of the combination of poly(A) and         histoneSL on protein expression from mRNA in vivo,         Luciferase-encoding mRNAs with different sequences 3′ of the         alpha-globin 3′-UTR or control mRNA were injected intradermally         into mice: mRNAs contained either an A64 poly(A) sequence or a         histoneSL instead, or both A64 poly(A) and histoneSL 3′ of the         3′-UTR. Luciferase levels were measured at 16 hours after         injection (see following Table 12 and FIG. 23).

TABLE 12 RLU at mRNA 16 hours ppLuc(GC)-ag-A64- 38081 histoneSL ppLuc(GC)-ag-histoneSL 137 ppLuc(GC)-ag-A64 4607

-   -   Luciferase was expressed from mRNA having either a histoneSL or         a poly(A) sequence. Strikingly, however, the combination of         poly(A) and histoneSL further strongly increased the luciferase         level, manifold above the level observed with either of the         individual elements. The magnitude of the rise in luciferase         level due to combining poly(A) and histoneSL in the same mRNA         demonstrates that they are acting synergistically.     -   The synergy between poly(A) and histoneSL was quantified by         dividing the signal from poly(A)-histoneSL mRNA (+/+) by the sum         of the signals from histoneSL mRNA (−/+) plus poly(A) mRNA (+/−)         (see following Table 13).

TABLE 13 RLU at A64 histoneSL 16 hours + + 38081 − + 137 + − 4607 Synergy 8.0

-   -   The factor thus calculated specifies how much higher the         luciferase level from mRNA combining poly(A) and histoneSL is         than would be expected if the effects of poly(A) and histoneSL         were purely additive. The luciferase level from mRNA combining         poly(A) and histoneSL was 8 times higher than if their effects         were purely additive. This result confirms that the combination         of poly(A) and histoneSL effects a markedly synergistic increase         in protein expression in vivo.

11. Antibody Expression and Characterization

Cell Lines

-   -   RNA-based expression of humanised antibodies is done in either         CHO-K1 or BHK-21 (Syrian hamster kidney, HER2-negative) cells.         The tumour cell line BT-474 strongly expresses HER2 and is used         to record antibody levels by FACS analysis. All cell lines         except CHO are maintained in RPMI medium supplemented with FCS         and glutamine according to the supplier's information. CHO cells         are grown in Ham's F12 supplemented with 10% FCS. All cell lines         can be obtained from the German collection of cell cultures         (DSMZ, Braunschweig, Germany).

Antibody Expression

-   -   Various amounts of mRNA (G/C enriched as defined by the FIGS. 24         and 25) encoding the humanised antibody Herceptin (Trastuzumab)         is transfected into either CHO or BHK cells by electroporation         (300 V, 450 μF for CHO and 300 V, 150 μF for BHK). After         transfection, cells are seeded onto 24-well cell culture plates         at a density of 200.000 to 400.000 cells per well. For         collection of secreted protein, medium is replaced by 250 μl of         fresh medium after cell attachment to the plastic surface.         Secreted protein is collected for 24-96 hours and stored at         4° C. In addition, cells are harvested into 50 μl of phosphate         buffered saline (1×PBS buffer) containing 0.5% BSA and are         disrupted by three freeze-thaw cycles. Cell lysates are cleared         by centrifugation and stored at −80° C.

Western Blot Analysis

-   -   In order to detect translation of transfected RNA, proteins from         either cell culture supernatants or cell lysates are separated         by a 12% SDS-PAGE and blotted onto a nitrocellulose membrane.         The humanised antibody Herceptin (Roche) can be used as a         control. After blotting is completed, membranes are         consecutively incubated with a biotinylated goat anti-human IgG         antibody (Dianova), streptavidin coupled to horseradish         peroxidase (BD), and a chemiluminescent substrate (SuperSignal         West Pico, Pierce). Staining is detected with a Fuji LAS-1000         chemiluminescence camera.

FACS Analysis

-   -   Functional antibody formation can be demonstrated by FACS         staining of antigen-expressing target cells. In order to examine         the production of functional antibodies, cell culture         supernatants of RNA-transfected cells are collected after 48 to         96 hours. Approximately 200.000 target BT-474 cells expressing         HER2 are incubated with either control antibodies (Herceptin,         Roche) or cell culture supernatants. For detection of bound         antibodies, cells are stained with biotinylated goat anti-human         IgG (Dianova) and PE-labelled streptavidin (Invitrogen).
